| 摘要: |
| 野外和室内试验表明，用6osoXI型时域反射仪(TDR)测定土壤含水率与中子仪法相比，速度快，精度高；还发现随着导棒长度的增大，TDR与烘干法测定结果的偏差有所增大，文中给出了5种导棒长度的校正公式。 |

| Abstract: |
| The results of field and in-door experiments and comparison with Neutron Probe showed that the 6050X1 Time-Domain Refleetometry (TDR) had high preeision and speed in measuring soil water content,also the longer the wave guides is,the
bigger the variation error in the results measured with TDR.This paperpresents five adiusting formulas for the length selcetion of water guides. |
| Key words: Time-Domain Reflectometry,soil water content,measuring precision,neutron probe |
